@four4college You should look at what each class the challenge/AP exams map to satisfy for NUpath and see what’s missing. Generally though yes, I would expect some things still to be left, though it could be as little as 1-2 classes if you have a wide enough breadth of incoming credit.
For writing specifically, AP credit can be used for one course, but you will still need the advanced writing course, as well as the two writing-intensive classes satisfied by all majors. It does not appear they are offering a challenge exam for that likely given the level of detail needed to grade writing exams, while the subjects they chose are much more objective.
